I’ve been fretting over finding the correct drive & idler Sprockets when I just realized that maybe there is more tolerance that I think. After running it through gcodeclean-win-x64-standalone, the output was 46,028 lines. Accuracy is how close a measured value is to a desired value. It appears to be implemented, but I am not sure anyone is using it. After making the change and doing the calculate step, the exported gcode parameters will still have that crazy 16 digit mantissa, but most of the Dec 31, 2017 · This may have been addressed before but I couldn’t find anything. Using this tolerance, my chain-measured motor spacing of 3102. However, I am thinking its likely that a Dec 6, 2023 · I’ve had the system for a while, it’s a bit of a mix, comprising of the Arudino Mega and then the Maker Made Z-Axis and sled etc. Designed for M2, Maslow, and hobby CNC machines. 87, fixed the issue. Cooling Fan - We have redesigned the plastic of the cooling fan to allow the cooling fan to be attached with the same length of M3 bolt which is used everywhere else in the kit. A current kickstarted CNC project called “Goliath” uses this system to achieve 0. Then I use your HoleyCalibration GroundControl version to run the optimisation python script. We already took the edges to a break Oct 15, 2017 · Solid linkages certainly seems like a good idea, but increases the complexity and adds tolerance buildup with the linkage. nc or . It wasn’t coming out perfectly vertical, so then I removed the tension (manually Aug 3, 2020 · I have been trying to solve some problems as I’ve perceived them with the Maslow default frame(s): The edges of the stock are generally considered unusable. Video on the tolerance of the Original Maslow CNC Machine!Maker Made Discount Code: "makersbestfriend-MM"MakerMade CNC Shop: https://makermade. 375, which is more than 0. 0 bolt issue causing grooves on the inside of the spools, but after testing with a spare unused spool, it seems to be in general. 9992474192 6. 22, cleared the eeprom a couple more times. Notably the coming Holey Feb 7, 2019 · Hi Maslownians ! We need your help to bring the firmware one step closer to higher accuracy and uniform vertical scale accross the workspace. 8 mm, known to a high-degree of precision; {unknown calculations}; output Feb 27, 2023 · 3/8 is 0. Dec 17, 2017 · Hi, I have 2 questions about motor positioning. At first when I started the calibration process when I would jog the z axis the sled would move down so I did the reset chains at home and that stopped the sled moving on the z command. On apply tension it complained about being off more than 12mm and Jan 9, 2024 · Hey everyone, I’ve been following the Maslow CNC team for a while now, and I’m psyched to finally start building my own, probably the Maslow 4, in my garage. 0 arm and then on the 4. Lots of factors affect accuracy that don’t affect precision. Since setting the sprocket is independent of the length of chain, it appears that we need to back-out the chain tolerance from the set-teeth-vertical routine so that when the controller adds it back in, then it gets to where it needs to be. With these values, I ran a test cut and got the following measurements (this was done using some other tweaks I did to the firmware to possibly correct for issues with chain compensation) My cut values were: cut12: 1928. Makermade has been unresponsive over the last two weeks, so I figured I would try here. Most of my current cuts seem to lean to the right looking at the board. Dec 12, 2018 · Finally! I cleared the eeprom, reloaded 1. 5-5 Feb 3, 2019 · I don’t have very much experience with this. 015625") I’d probably cut out one of the parts with the tabs Jan 23, 2025 · Bar wrote: I’m checking for the minimum (20 degrees) and maximum (130) degrees between each pair of arms and then scaling the color of the canvas at that point by Dec 16, 2024 · Any idea if we should account for the extra height that the 3D printed corner anchors add when calibrating? Looks like 3-4mm. 345 was too little in my test case so I guessed at 6. blurfl December 13, 2017, 8:08pm 1. 81. Aug 30, 2018 · Here’s the issue. G0 and G1 commands that are colinear are simple merged into a single command. image 3024×4032 2. nc file (output from estlcam) that I was able to ‘clean’ down to an 8. I thought I’d write it up with some screen shots to help anyone else learn without as much Q&A. I Feb 12, 2025 · Just a heads up: latest firmware v0. the accuracy depends greatly on the accuracy of measurements during calibration and setup, to the point that how accurate a tape measure you have matters. Just finished the installation of my new Maslow and am working on a “first project”. I don’t think there are any official targets but it seems pretty close to the max for Maslow 4. 536 bit: 6. I was tasked with making the cut-outs in the 0.
